Many embedded systems typically don't need them. This removes about

Many embedded systems don't need the full POSIX timer support.
Configuring them out provides a nice kernel image size reduction.

There were two net sysctls that could be written from unprivileged net

To fix the existing issues and prevent stuff this from happening again in

nf_log_proc_dostring() used current's network namespace instead of the one
corresponding to the sysctl file the write was performed on. Because the
permission check happens at open time and the nf_log files in namespaces
are accessible for the namespace owner, this can be abused by an

This patch depends on the pending changes to ip/iplink_vxlan.c as as
well as on IPv6 support in vxlan. I'll rebase and resend it once all
the changes to vxlan are merged.
Was this one (and related) ever merged?

commit 1a6509d99122 ("[IPSEC]: Add support for combined mode algorithms")
introduced aead. The function attach_aead kmemdup()s the algorithm
name during xfrm_state_construct().
However this memory is never freed.
Implementation has since been slightly modified in

When enablement of the SRIOV e-switch in certain mode (switchdev or legacy)
fails, we must set the mode to none. Otherwise, we'll run into double free
based crashes when further attempting to deal with the e-switch (such
as when disabling sriov or unloading the driver).
